So, while I was looking after my son who was ill yesterday I finally completed my E3DV6 conversion. I will say yes it prints better than stock. But one thing I have noticed. After printing out an item and you leave it for a little while then try and print again it jams in the nozzle. When I pull out the filament it is like its been warped at the hotend. Any Ideas on this please? Also I am thinking of replacing my stepper motor to one which will work with Flex as it still jams up.

The real question: How can i stop it from jamming in the Stepper motor which is feeding in to the bowden tube? Is there anything I can print out to help?
